Title: Cardiac pump with pulsed action - has microprocessor controlled stepping motor acting via screw mechanism on pump diaphragm
IPC: A61M60/569
Filed: 1979-06-11
Abstract: The cardiac pump providing pulsed assistance includes a cover (14) mounted on a variable reluctance stepping motor (13). The drive shaft from the stepping motor extends vertically and is attached by a screw mechanism to a plate (15). The plate in turn is attached to a flexible membrane (16) which forms the lower surface of the pump chamber. Movement of the stepping motor directly affects the volume of the pump chamber. Input (17) and output (18) orifices are provided with valves controlling the flow of liquid. The stepping motor is controlled to make a series of incremental steps in the two directions by a microprocessor circuit. The same microprocessor is responsible for the control of the inlet and outlet valves. The pump provides a pulsed flow of blood akin to the natural heart action, which helps to ensure good transfer of blood to the body tissue.

Title: Solar heater for production of hot water - has storage reservoir with graduated temperature levels caused by heat flowing through slots in vertical tube
Inventor: LANDREAU ANDRE
IPC: F24H1/20
Filed: 1979-07-13
Abstract: The vertical, insulated reservoir (10) is mounted on a lower, insulated container (10a) enclosing a volume (V). Domestic water is supplied at low level (30) and drawn off at the top (31). The solar collector is connected to the heat exchanger (15) by the flow pipes (15A,15B). The heat exchanger is enclosed by an outer cover (20,20A) and an inner sleeve (22a) to produce a reduced volume (C). The flow tube (21) extends vertically from the upper region of the volume (c) through the reservoir (10). Slots (21A,21B) are formed in the tube so that a circuit exists between the volume (C) and the reservoir (10). Water entering at the inlet (30) passes over the heat exchanger (15) and is heated to a temperature relative to the solar radiation. The heated water passes through the holes (21A) and exits into the reservoir at a level where the temperature of both heated and stored water are equal.

Patent FR-2445120-A1 (FR)
IPC: G04B37/16
Filed: 1979-12-26
Abstract: Disclosed is a watch band end attachment adapted to be releasably and adjustably mounted between the spaced lugs of a watch. The end attachment of the invention typically includes a housing, one end of which fits between the spaced lugs and the other end of which is connected to the watch band, and levers on opposite sides of the housing with a sliding member therebetween. The levers have lug-engaging ends disposed in the first end portion of the housing and pivot ends in the second end portion. Cam surfaces of the levers coact with cam-engaging surfaces of the sliding member as the latter is translated from the pivotal ends toward the lug-engaging ends of the levers to cause the lug-engaging ends to pivot and extend through the side apertures in the housing and engage the lugs of the watch. Reverse movement of the sliding member disengages the end attachment from the watch. Accidental disengagement is prevented by locking means typically in the form of a spring associated with the levers or sliding member. Attachment and detachment is accomplished by simple manipulation of a finger tab connected to the sliding member and accessible from outside the housing.

Title: Double sleeve filter unit to remove dust from gases - having rotating suction pipe with nozzles below the sleeve inlet to clean sleeves
IPC: B01D46/04
Filed: 1980-05-29
Abstract: Filter unit consists of double wall cylindrical sleeves, the dirty gas being blown up the annular space between the two sleeves. The sleeves are firmly supported at the top and the inner sleeve has a spring mounting at the base. To clean them, a suction pipe is mounted below the inlets on a rotating flange coupling. This rotates around and subjects all the sleeves in turn to suction and thereby a reverse gas pulse. This discharges the dust and allows it to flow over to a cyclone collector. Coarse material is removed from the base. Used for removing dust from gas streams. Arrangement gives a simpler and more reliable system than shaker or reverse pulse systems.

Title: Dual purpose domestic mixer tap - has extra valved outlet to washing machine tapping from hot and cold feed passages before mixing chamber
Inventor: RUTH ANDREAS
IPC: D06F39/08
Filed: 1980-09-05
Abstract: The combination mixer tap may be used on domestic sinks, also providing a controllable mixed water feed (54) to e.g. a plumbed in washing machine. A table (4) mounted tap body (1) receives cold (21) and hot (31) water feeds through a table opening(41)' providing separate internal conduits (32,33,22,23) to a mixing chamber (61). Each conduit may open out onto the body exterior (2,3) to accommodate flow control valves of e.g. the screw-actuated lift type, the chamber (61) communicating with a further open well (6) for a draw-off valve. A further body well (52) locates an additional valve controlling flow to a supplementary tapping (54), having an invert hole (53) communicating with an outgoing feed pipe (54) through the table opening (41).Ancillary conduits lead from the hot and cold feed passages, being located upstream of the mixing chamber, and each opening out (51a) in the well invert.
